Y., A ooaron-a'rron or DELAWARE rrrnwarrnfe Macirnm Application filed March 12, 1928. Seri l No. 260,34 able towithstand the dead weight. said" This invention pertains to typewriting machines, and more particularly to a means for mounting portable models on a baseboard forming part of a carrying case.

Portable typewriters are constructed as low as possible. The feet of the typewriter are made low, and extend but slightly below the frame. The shallow recesses, on account of small wall area, have very little hold.-

ing power, and have proven unsuitable, because it has been found that, in carrying the typewriter from place to place, the edges of said recesses have become chipped or otherwise damaged, and cease to properly function. A purpose of this invention is to overcome the present failings, and to furnish additional advantages. To accomplish this, hanger-plates are fastened on top of the baseboard above the recesses.

After afiixing said plates, the typewriter is placed in position on the baseboard, and the feet or supports pass through holes in the plates and extend into said recesses, which are oversize, so that the typewriter, when being carried about, hangs upon the hangerplates.

The addition of said hangar-plates does not increase the height of the typewriter above the baseboard, because the thickness of the plates lies within a clearance space between the frame of each typewriter and the bottom surface of its feet, which (when the machine is in normal working position) rest upon the floors of the oversize recesses.

When the baseboard with the typewriter thereon is in a vertical or carrying position, the weight of the machine is primarily carried by its feet, which usually are of rubber. The weight upon said feet is carried by the hanger-plates, such weight being distributed through the lower surface of the plates to the baseboard. The weight of the typewriter is distributed, when hanging or carried vertically, to eight points on the baseboard. A result of such wide distribution of weight is a lessened strain at each of the points on the baseboard where such weight is transmitted. This again results in a more enduring base.- board, if kept at its customary thickness, or permits the use of a thinner baseboard, still hanger-plates also afford somemeasureof reinforcement agalnst exterior blows on the baseboard when the latter forms part of a carrying case.- Y

' In carrying out this invention, I provide a baseboard 10, having in' its upper surface a plurality. of recesses 11 into which extend resilient feet 12, fastened by screws to a typewriter-frame 13. Metallic reinforcing bush- IIIgS 14 are preferably mounted-in the baseboard 10,- and internally threaded to receive set screws '15or-anchoring screws 16.

' Secured to "the baseboard 10 by the set screws 15 are the'two hanger-plates 17, in

the positions shown by Figure 3. These plates 17 formtwo units, each one performing the same functions respectively for two feet or supports,Yon each side frame of the typewriterj; Each hanger-plate is ofelongated shape, and includes-apair of annular portions 23 having foot-size openings 24', the

recesses 11 beingoversize, so that, when the hangers 17 are in position on the baseboard,

the edges of the openings 24 just overlie the edges ofthe oversize recesses 11, and thereby sustain'theweiglit of the machine when being carried about: The recesses 11 are made oversize,'to allow for slight alterations in. the size :ofthe baseboard from the usual causesi l Forwardly-e'xtending brackets 18 are secured respectively to flanges, near, the front of and. oneach side portion of the type- ..writer-frame,asbest shown in Figure 1, said brackets being held to the frame by rivets or diameter than the shanks of'anchoring screws rated bushings extending through the baseboard and means passing into the bushing through the hanger plate to hold the hanger plate and frame from moving perpendicularly from said board.

16, only the threaded portion'of the latter can be passed through. When thishas. been a done, they are screwed into threaded under lying bushings set into the-baseboard. This not only holds down the typewriter-frame,

but also anchors the ends'of said plates 17, and co-operates with. screws 15 extending throughopenings 26 and threaded into bushings 14 to rigidly hold said plates to the base board. Other anchoring means .QQ'a-t-the rear of the machine co-operates with the front anchoring means to retain thetypewriterframe 13. Asthe clearance between the typewriter-frame and the baseboard should be maintained atxa minimum, and as there is. a

projecting screw-head 28 below the bottom of each side frame of the typewriter, a clearance hole 27 is cut in'each platel'i, into which said screw-head can project.

Variations may be resorted to Within the scope of the invention, and portions of the improvements may be useclwithout others.

Having thus described 'my invention, I claim: 5

hanger plate havingits parts in a single plane, said hanger plate having a perforation near each end throughwhich the. feet may be inserted and withdrawn perpendicular to said plate, means for fastening the plate to said baseboard, said means passing through the base board and typewriterframe for pmventing the frame from. moving; perpendicularly from the base board.-

2. Means for'fastening a typewriter frame having feet to a baseboard, comprising, a hanger plate havingits parts ina single plane, said hanger plate having a perforation neare-ach end through which the feet maybe inserted and withdrawn'perpendicular to said plate, said board having sockets opposite said perforationsinto which said feet may extend, means forfastening the plate to said baseboard, said means passing through the base board and typewriter frame for preventing the frame from moving perpendicularly from the base board.
